Silent install Hyperion 9.3 plugin

I've got a .bat file that works flawlessly if I manually run it. But when put in a GPO as a startup or shutdown script it does not. As a startup script it does nothing. As a shutdown script it stops for 10-15 min at "running shutdown scripts" but it dosent install.
Do you guys see anything differnt I should do or how I should start my trouble shooting?

But I figured it out.
I was using the IP address in the path. This apparently does not work. As soon as I changed it to the server name it started working!!! And after some tweaking this morning I now have this, and i'm about to start some more testing with our remote sites.
